'.vn ot' ilul opi-ing in vontvolling i with the inrnae and metal pot, so that the' metal will flow directly into the casting box, to make the plate. The Casting apparatus or mold may be used separately if preferred, and consists of the core or cope, which is stationary, and the box or drag which holds the matrix and the plate after it is cast, und is pivotally mounted on a movable support, and has a pivotal motion to be moved into an upright position contiguous to the core or cope, to receive the metal and into a horlzontal position `for the removal of the plate. The means for moving the box or drag into its upright position and holding it against .the core or cope, and moving it into its horizontal position, consists preferably of a knuckle joint mechanism operated by a single lever. The core or cope 18 is hollowed on its inner surface, and of circular shape in cross section, corresponding to the shape of the plate to be cast, as is customary, and ex tends in a vertical direction around the convex circular extension 1' on the furnace 1 and is secured thereto in a fixed or stationary position. A piece of heavy sheet iron 19, (see Fig. 4), in this instance extends upon the inside of the core 18, and between it and the extension 1', and is used as a water shield or rotection to said extension. The lower end ci) the sheet iron 19`has open ings therein, through which the connections 17 extend, and the sheet iron around the openings is made to rotect the connections 17, and guide the Water away from the same, see Figs. 7 and 8.

A water pipe 20"', see Fig. 4, provided with perforations, extends within the up er part of the core 18 and the water passes wetv'een said core and the shield 19, and serves to keep the corei18 from becoming too hot. The core 18 has a series of horizontal grooves 18' therein, as is customary, and also a series of vertical grooves 18", extending from thc upper horizontal groove 18', as shown in Fig. 2. The grooves 18 allow the metal, as it runs into the casting box, to form the connecting part 20', between the cast plate 2'), and the slug 20, see Fig. 10. The slug 20 will ordinarily drop oi of the plate 20 of its own weight, when the cast plate` is transferred to its supportin holder or block, as will be hereinafter descri ed.

The casting box or drag is preferably made in two parts, and so constructed and operated, that both parts have a pivotal or swinging motion in a vertical plane, to carry the matrix into position, contiguous to the core 18, for the plate to be cast, and one part, which supports the plate after it is cast, has a pivotal motion at right anglesI to .the first mentioned pivotal motion, to raise, and transfer the cast plate Aonto its supporting block. I

The main part 21 of the casting box, which only has one pivotal motion, has a trunnion 22 extending out from each side thereof,

which act to pivotally support the drag or main part 21 on its movable sup ort, consisting in this instance of two roc ing bars or levers pivotally connected at one end to the trunnions 22, and pivotally supported at the other end on a transverse rod 24 extending between the sides of the frame-work 25, in this instance secured to the furnace 1. The levers or rocking bars 23, forming the movable support, are operated by a. knuckle joint mechanism, comprising the arms 26 and 2T, pivotally connected, and the arm 27 fast on a shaft 28 mounted in bearings on the frame 25. The shaft 28 has an operating arm 29 fast thereon, to turn said shaft and oper ate the knuckle joint mechanism, to move the casting box and carry it from its horizontal position to a vertical position, when the plate is to be cast, and then return it to a horizontal position.

In connection with the casting box and its supporting mechanism, I employ a counterbalance device, consisting in this instance of a rod 30, (see Figs. 4 and 11), pivotally attached at one end the lower part of the box 21, and guided and sliding through an opening in a part 31 suitably supported, on the frame 25, and having an expansion spring 32 thereon, compressed between the stationary part 31, and a pin 33 in the end of the rod 30. Said rod 30 acts to hold away the bottom or lower end of the casting box, from the core 18, when the box is raised, until the box reaches its vertical position; it also acts to first move the bottom, or lower end of the casting brx away from the bottom of the core 18, when the casting box is moved Into its horizontal position, allowing the cast plate to free itself from the recesses or corrugations 1Q and 18" in the core 18. The yrod 30 also'acts to hold the casting box in its horizontal position. The rod 30, as is obvious from Fig. 11, causes the box to turn over as it moves orvvard under the tdggle action. The spring 32 bearing on the rod 31, holds the bottom of the box away from the core until the box is completely turned over and is then compressed by the toggle action allowing the box to move bodily toward and into contact with the core. This action will be clearly obvious from the construction shown by full and dotted lines in Fig. 11.

In connection with the part 21 of the casting box, and forming a part of the casting box, is the matrix and plate carrying frame 34, pivoted at one edge to the part 21 by a sha t 3,5, which extends through lugs 21', on the part 21, and lugs 34', on the frame 34, see Fig. 1. The frame 34 has a` pivotal motion with the part 21, being connected there to by a clamp, or lock 36 ivoted to swing on a pin 36' located on t e bar' 34". This clamp is operated by a handle 37, (see Figs. 2, and 3), and also a pivotal motion independent of the part 21, to raise the cast plate support the cast 20, as shown in Fig. 6, and transfer it to the plate holder, or block. The frame 34 in this instance is madebf two rigid side bars 34, and the three transverse hinged bars or rings 38, 39 and 40, see Fig. l. The hinged or flexible bars or end rings 38 and 39 are beveled on their inner edges, and said edges plate 20, when the plate is being transferred to the supportin holder or block the ortions 20 interme iate the plate 20 and t eslug 20, extend orerthe bar 39, and the slu 20 extends between the bars 39 and 40. T e matrix 41 extends upon the underside of the bars 38 and 39, at its edges, and its ends extend between the ma trix side bars 42, extending upon the inside of the side bars 34, and said bars 34. The bars 42l are connected with eccentries 43, on shafts 44, journaled in the side bars 34, see Fig. 5. The shafts 44 are provided with handles 45, (see Fig. l), to turn them and move out the bars 42, so the ends of the matrix can be inserted between said bars 39, and the side bars 34, and then said bars 42 moved back to hold the matrix in place. The matrix in this Way` will be firmly held in place and not removed with the east plate.

Y The edges of the cast plate 20 will extend under the bars 42, which serve to hold the plate in the frame `34 when said frame is raised, or moved over, .to transfer the plate on to the plate holder or block. 0n the outer end of the frame 34 isa rigid har or yoke 46, pivoted at one end on a pin 47, fast in the frame 34, and provided with an oflset or angular slot 47', at its other end, (sec Fig. 3), through which loosely extends a headed pin 48, secured to the end of the frame 34, to attach the slotted' end of the bar or yoke 4t to said frame 34. The shape of the oll'set slot 47( is such, that when bthe frame 34 is raised to, transfer the'plate to the block,` the pin 48 will extend in one portion of said slot, as shown in' Fig. 3, and in euch a position, rela tively to the slot 47', as to rigidly attach the end' ofv the bar or yoke 46 to the frame 34, and thus hold the transverse hinged bars 33. 39, and 40 in a rigid, osition, duringr the raising of the frame. fter the frame 34 is raised and superimposed upon the plate holding block 53, the engagement of the outer edge of the frame with the cam extenY siOns on the block, to be hereinafter doseribed, will cause the pin 48 to more ont of one portion of the slot 47 into the other portion of said slot, as shown in Fig. 6. and al'- lows the transverse hinged hars 38, 39. and 40 to spread or move apart. to release the cast plate.v l,in the manner to be hereinafter described. if' Vhen the frame 34 is returningr to its first position, the pin 43 remains` in tlnl saule portion of the slot 47', and acts to hold the transrerse hinged bars 38. 3i) and It() apart, so that. the outside bar 42 will not come in contact with the plate and injure it.

4 l l l l i After the frame 34 is returned to its lowered position, the tion of the slot 4T', first above mentione to hold the bars 38, 39 and 40 rigidly. The frame 34 is raised, to transfer the cast plate to the plate holder, in this instance by means of a foot treadle 49, secured on a rock shaft- 50, journaled in the frame 25, through an arm 51, fast on said shaft, and a lever,52 slotted at its upper end to receive the pin 47, which is held therein when the treadle mech anism is operated, but is withdrawn when the whole casting box is moved into its vertical position.

I will now describe the plate holder, or block onto which the Cast plate is transferred from the casting box, by the frame 34. ahore described. The plate holder or block in this instance consists of a cored casting 53, perforated on top, and connected with a water pipe, as 54, Fig. 3, through which water passes to Cool the plate. The holder or blot-l 53 is of a shape corresponding to the shape of the cast plate 20, and is preferably secured at one edge to a hinged frame 55, mounted on a shaft, 5G, journaled on the frame 25. ingly held up in normal position in thisl instance by a spring actuated rod 57, having an expanding spring 58 encircling its lower end, see Fig. W'hen the rast plate 20 is transferred hy the frame 34 onto the holder or block 53, the weight of the plate will depress the holder or hlork 53, and the cam extensionsI 53` on the outer edge of the holder or block 53 being engaged hy the outer har 42 of the fl'ame 34, will cause the hinged harsl 35. 39,` and 40 to spread, to release the cast/,plate 20 from the outer har 42, andat the same time draw the matrix -41 away from the'plate, releasing the natrix and leaving. the cast plate 2() on the holder 5P., see Fig. G. hinged har referred to, the slotted end of the yoke 4G falls forward and the pin 47 engaging the slot holds the hinged hars in their spread position. ln this wav the har 42 will pass on the outside of thc plate 20 now resting on thr holder when the frame 34 is returned to its position in the hox 2l. I have shown a valve 59, (see Fig". fl), for antonialirally controllingl the flow of water through the pipe 54 lo the holder 53, operated hy a fixed rod 60, to open the valve. when the holder is pressed down by the weight of ilu` cast plate thereon. and to close the valve when the plate is removed, and the holder ,33 rifas.

lfroni .the ahorn description in connection with the dran ings, the operation of my ap` params t'or makingY stereotype plates will he readily understood hy tht-se skilled in the nrt. and briefly is as follows: After the metal placed in the pot .i i sullllientlymelted hy the heat troni the furnace, the apparatus The holder or block 53 is yield` Durinfr the sn'oadinrf of the Y is ready to,be used. The casting box 21 is in a horizontal position, as shown in Fig. 1. The two bars 42 are moved out by means of the handles 45, as above described, so that the ends of the matrix can be inserted between said bars 4Q and the rigid side. bars 34", and then said bars 42 are moved back to bind or hold the yends of the matrix between the bars 4Q and the bars 34, as shown in Fig. 5. The end rings 3S and 39 rest -upon the flat margins of a flexible matrix, and force the same into proper curvature against `the bottom, the edges adjacent to the type or impression face being slightly beveled under so as to overlap the usual raised margins formed between the impression face of the Inatlix and the flat margins. This beveling, for the purpose of overlapping the said ralsed part of the margins, is plainly shown in Fig. 4. Above this under cutting of the curved bars 38 and 39 the bars are beveled the reverse way, so as to form bev cled edges upon the plate, thereby forining means by which they can be attached to a cylinder of a printing press without the usual cutting. By this combination of overlapping the raised portion of the margins of a matrix, and formin the bevel, I am enabled to dispense with t 1e usual hand trimming, Vand the same beveled edges. which form beveled edges upon the plate, also serve as supports upon which the plate rests as the frame is raised and swings over to deposit the late upon the plate holder. By means ofJ the arm or handle 29. the knuckle joint mechanism is oper-fated to raise the casting box, carrying the matrix Ll1, from a horizontal position into a vertical position, and contiguous to the core 1S, preparatory to the plate being cast. The valves T are now opened by the revolution o f the, eccentric 8 b v the handle 11, through 1nter" mediate connections, to allow the metal to flow from the well G through the opening (3, and through the connections 1T, and up between the core 18, and the matrix il, to occupy the space in the casting box between the bars 42, 42, 3S, and 39, with the slug between the bars 39 and 40. `.Vater is turned on to flow through the pipe 20, between the sheet iron 19, and the core 18.

After asuflicient quantity of metal has passed thuough the valves, the valves are closed by turning the eccentric 8 in the opposite direction. The casting box is then moved back into its horizontal position, and the fra me 34 disconnected from the main part 21 ofthecasting box,aud raised by the treadle mechanism, to transfer thecast plate from the casting box onto the holder or block 51. The weight of the plate depressesthe holder 53, and as above described, the plate is released, the matrix 41 remaining in place, and the frame 34 is returned to its normal position in the casting box, ready for an other casting. Water is turned on from the pipe connection 54 to the holder 53, to cool the cast plate, preparatory to removal.

It will be understood, that the details of construction of my improvements in stereotyping maehines may be varied if desired. More than one casting box may be used if desired, and the casting apparatus or mold may be used separately and independently of the furnace, and melting pot if desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is r 1.
